Patented Aug. 30, A1932 i fi*- UNirEDsrres PATENr ori-ICE f HARLOW H.' HATHAWAY, OF LOS ANGELES, CALIFORNIA BUILDING CONSTRUCTION y.Application :filed September 15, 1928. SeriaI 110.306,137.

y` invention relatesto building constructions',"' and A'more particularly to lathing vwhereby a great bonding or clinching power is provided for has set, which materiall may be applied in the usual manner, either by hand or a pressure gun, as in practice desired.

As is well known, when the conventional wooden lath is used in building constructions, either on the inside or the outside of the building, it is necessary to soak the laths thoroughly with water to swell the same, so that after the plastic material is applied the lath will not swell and break the clincher and a more thorough clinching or bonding action is attained when said material sets and the lath dries.

If this manner is not applied the plastic material usually results in the cracking of the set material, or even the dropping thereof, especially after a hard rain, or the overflow of bath tubs or the like, since the bond or key thus provided for the set material is l slight and easily broken, even when not subjected to accidental soaking of water. Moreover, the laths are frequently set too close together or too far apart, in both cases resulting in an ineffective key or bond to hold the set plastic material to the lathing. In wetting the laths, also, the character of the wood used, with its hard grain, prevents said laths from readily absorbing the water, causing said laths to buckle, making a bump in ,l the wall, which by a sudden j ar of the wall '35 will cause the material to fall, which is frequently dangerous to the person or persons standing close by. By the use of my invention all of these deleterious results are i.' eectively overcome.

It is accordingly an object of my invention to provide a novel form of lathing having means on the edges thereof, which may be in the form of grooves of any preferred shape or form, the outer edges of said grooves either overlapping each other or being flush, said grooves functioning to receive and hold the water so the laths may be thoroughly soaked, the face of said laths, if desired being also provided with indentations, grooves,

in staggered relation, diagonally positioned a plastic material, after it` or otherwise, to receive the water, and later the plastic material, which, after it has set forms an effective key or bond to prevent the set material from cracking or falling, Vsaid laths, if desired being also provided with means whereby they maybe secured in place on the building.

The aboveA and further objects and advantages of my invention as will hereinafter more fully appear, I attain by the construction described in the specification and illustrated on the'drawing, forming a part of my application;

Reference Y is had to the accompanying drawing, in which similar reference characters denote similar parts. In the drawlngi i Fig. 1 is a fragmentary front elevational view showing the laths in place, the plastic material being cut away to disclose same,

Fig. 2 is a cross-sectional view, taken on the line, 2 2, Fig.r l, looking in the direction of the arrows,

Fig. 3 is a fragmentary side elevational view of a lath showing oneform of indentations,

Fig.V 4 is a cross-sectional view, taken on the line 4 4, Fig. 3, and

Fig. 5 is a View similar to Fig. 3, but illustrating alath equipped with diagonal indentations. i

Describing my invention more in detail, while I preferably employ wood to form my novel' form oflath, it is clear that other material may be used, the wood being preferably sawed or cut to the regulation size, and

provided vwith grooves, holes, and indentations, to `hold the water a sufficient time to soak the lath, and to break the hard grains which cause practically all the buckling, and enables the set plastic material to make a perfect clinch or bond. y

It is to bevunderstood that the term lath as used in the specification and claim is of the standard type, such as used in practice, which is substantially from 82 to 48 long, ML to /g thick and l to 11/8 in width.

As seen in the drawing, 2 incidates a lath, preferably of wood, adapted to be secured to the studs 4 by nails or any other preferred 3 .Y 45 indentation formsan eii'ectivekey or clinch,
